Hey guys, any help at all or direction would be greatly appreciated. I do not even know what is causing this. I think it is something corrupt and when the chunk loads the server throws this and stops. The problem is, the server does not even tell me where the problem is. I have fixed this twice by noticing that it crashes after a certain player joined and went in and regenerated the area where they were via WorldEdit. And a day later I am getting a similar error. Even if I have to reset the map, I still need to know what causes this.
